Superconducting Qubits: Latest IBM, Google & Rigetti Developments
Latest superconducting qubit news: IBM Quantum, Google Willow chip, Rigetti Novera. Cryogenic systems, error correction & quantum supremacy updates.
Superconducting qubits represent the most commercially advanced quantum computing technology, powering systems from IBM, Google, and Rigetti. These quantum processors leverage Josephson junctions—superconducting circuits that create non-linear inductance—to generate controllable quantum states at temperatures near absolute zero (15-20 millikelvin).
The dominant superconducting qubit design, the transmon qubit, balances coherence time and control simplicity by reducing sensitivity to charge noise. Recent breakthroughs include Google's Willow chip achieving below-threshold quantum error correction, demonstrating that increasing qubit count can actually reduce errors—a critical milestone for fault-tolerant quantum computing. IBM continues scaling its Heron processor architecture toward 1,000+ qubit systems while improving gate fidelities above 99.5%.
India's National Quantum Mission & Superconducting Qubits
India's National Quantum Mission (NQM), approved by the Union Cabinet on 19 April 2023 with an allocation of ₹6,003.65 crore for eight years (2023-2031), prioritizes superconducting qubit development under its Quantum Computing Thematic Hub. The Foundation for QC Innovation at IISc Bengaluru serves as the lead institution for this hub, working with IIT Delhi, IIT Bombay, TIFR Mumbai, and other institutions. The Tata Institute of Fundamental Research (TIFR) in Mumbai has established dilution refrigeration laboratories capable of operating at ultra-low temperatures to support superconducting qubit research. In August 2024, DRDO scientists from the Young Scientists Laboratory for Quantum Technologies (DYSL-QT), in collaboration with TIFR and TCS, completed end-to-end testing of a 6-qubit superconducting quantum processor with a novel ring-resonator design. This system includes a cloud-based interface developed by TCS for submitting quantum circuits and receiving computed results.
The NQM targets developing intermediate-scale quantum computers with 50-1000 physical qubits in eight years using various platforms including superconducting and photonic technology. Indigenous development of quantum fabrication facilities is underway, with IISc Bengaluru and IIT Bombay establishing quantum computing fabrication facilities under a ₹720 crore investment announced in November 2025. These facilities will support superconducting, photonic, and spin qubit technologies.
Key Advantages
Key advantages of superconducting qubits include nanosecond gate speeds enabling rapid algorithm execution, established semiconductor fabrication processes supporting manufacturing scalability, and a strong cryogenic infrastructure ecosystem. Current challenges include decoherence times (100-300 microseconds) that remain shorter than trapped-ion alternatives, error rates requiring extensive quantum error correction overhead, and cryogenic operation demands for specialized infrastructure.
Major Players
Major global players include IBM Quantum with cloud-accessible systems (Eagle, Osprey, Condor processors), Google Quantum AI focusing on error correction and quantum supremacy demonstrations, and Rigetti Computing offering hybrid quantum-classical systems. In India, the Foundation for QC Innovation at IISc, TIFR Mumbai, and IIT Bombay are building national capability with NQM support, while startups including QpiAI India are working on superconducting quantum computers.

Hood View a PDF of the paper titled Vapor Phase Assembly of Molecular Emitter Crystals for Photonic Integrated Circuits, by Arya D. Keni and 7 other authors View PDF HTML (experimental) Abstract:Organic molecules embedded in an organic matrix exhibit lifetime-limited optical coherence and bright emission at cryogenic temperatures below 3 K. Here we present a simple vapor-phase growth method for synthesizing optically thin DBT-doped anthracene crystals that are compatible with integrated nanophotonics. The crystals are ~200 nm thick with sub-nm surface roughness and a tunable lateral dimension of up to 200 $\mu$m. The molecular transitions remain narrow and spectrally stable, with inhomogeneous broadening below 100 GHz, comparable to DBT in bulk anthracene. The dopant density is tunable up to several hundred molecules per $\mu$m$^2$, ensuring emitters within the near-field of nanophotonic structures. We demonstrate that the crystals can be micropositioned onto integrated photonic devices with the molecular dipole aligned to the optical mode. This approach opens a path toward on-chip single-photon sources and collective many-emitter effects.

quantum-computingNQFF and Qolab Collaborate on Wafer-Scale Cryogenic Filters for Quantum Scaling
NQFF and Qolab Collaborate on Wafer-Scale Cryogenic Filters for Quantum Scaling The National Quantum Federated Foundry (NQFF) and Qolab have entered into a research collaboration to develop integrated cryogenic low-pass filters for quantum processors. The project aims to resolve hardware bottlenecks in scaling superconducting and spin-qubit systems by transitioning from discrete, bulky filter components to semiconductor-wafer-scale manufacturing. These filters are essential for shielding qubits from high-frequency microwave noise, which otherwise induces decoherence at millikelvin temperatures. The technical focus involves leveraging NQFF’s nanofabrication capabilities and Qolab’s systems expertise to produce filters directly on silicon wafers. This methodology allows for denser integration with qubit circuits and reduces the physical footprint within dilution refrigerators, facilitating the transition from dozens to millions of qubits. The resulting hardware is intended for deployment in quantum systems at the University of California, Los Angeles (UCLA). The National Quantum Office (NQO), hosted by the Agency for Science, Technology and Research (A*STAR), facilitates the partnership as part of Singapore’s National Quantum Strategy. NQFF utilizes a federated network including the A*STAR Institute of Materials Research and Engineering (IMRE), the A*STAR Institute of Microelectronics (IME), and the National University of Singapore (NUS). Qolab, co-founded by 2025 Physics Nobel Laureate Professor John Martinis, focuses on the development of utility-scale, fault-tolerant superconducting quantum computers.

Although spin and fermionic models have been extensively simulated on digital quantum computers, the simulation of bosonic systems on programmable quantum processors is often hindered by the intrinsically large Hilbert space of bosonic modes. In this work, we study the digital quantum simulation of bosonic modes using the Holstein-Primakoff (HP) transformation and implement this protocol on a cloud-based superconducting quantum processor. Two representative models are realized on quantum hardware: (i) the driven harmonic oscillator and (ii) the Jaynes-Cummings model. Using data obtained from the quantum simulations, we systematically examine the interplay between algorithmic and hardware-induced errors to identify optimal simulation parameters. The dominant algorithmic errors arise from the finite number of qubits used in the HP mapping and the finite number of Trotter steps in the time evolution, while hardware errors mainly originate from gate infidelity, decoherence, and readout errors. This study advances the digital quantum simulation of many-body systems involving bosonic degrees of freedom on currently available cloud quantum processors and provides a framework that can be extended to more complex spin-boson and multimode cavity models.

Gao View a PDF of the paper titled Flux-Activated Resonant Control of a Bosonic Quantum Memory, by Fernando Valadares and 6 other authors View PDF HTML (experimental) Abstract:Universal control of bosonic degrees of freedom provides a hardware-efficient route for quantum information processing with high-dimensional systems. Bosonic circuit quantum electrodynamics (cQED), which leverages transmon ancillae to coherently control long-lived superconducting cavities, is well suited to this goal. However, the cavity transitions are nearly degenerate in the usual dispersive regime, which limits the direct addressability of individual excitation levels and increases the complexity of engineered gates. Here, we integrate an on-chip flux-control architecture with a long-lived bosonic memory housed in a 3D superconducting cavity to dynamically access resonant Jaynes-Cummings (JC) interactions, and realize efficient arbitrary rotations between any pair of Fock levels in the memory. This on-demand access to JC interactions offers a versatile toolbox for implementing robust Fock-basis qudits and harnessing the rich dynamics of high-dimensional bosonic elements for quantum information processing.

quantum-computingClarification of “academic relevance”
Hi community, I’m reaching out to better understand the removal of my recent post regarding the quantum computer hardware replica I designed and built for a local university. It was removed for "not being related to the academics of quantum computing," and I’m hoping for some clarity on that criteria. To provide context: this wasn’t a fan-art project. This was a commissioned educational tool built specifically for a university’s quantum computing department. The "cooling tower" (dilution refrigerator) architecture is fundamental to how superconducting qubits function; without that specific hardware environment, the "academics" of the math and logic don't translate to reality. My post aimed to show the hardware side of the field, specifically how universities are using physical models to teach students about: Cryogenic environments and the stages of cooling. Signal routing and the physical constraints of wiring a quantum processor. Scaling challenges in hardware design. If a project commissioned by a university for the express purpose of departmental education doesn’t qualify as "academic," could you please clarify what does? Is the sub restricted strictly to theoretical papers, or is there room for the physical engineering and pedagogical tools that make the science accessible? I’d love to find a way to share this that fits your guidelines, as the intersection of hardware engineering and education is a vital part of the field. submitted by /u/StarsapBill [link] [comments]

Quantum computing is still a high-risk frontier, but for patient investors, these two tickers could be tomorrow's generational wealth creators.Quantum computing is still early, messy, and wildly speculative, which is exactly why the upside for patient, risk‑tolerant investors is so intriguing. If this technology can cross the chasm from lab curiosity to everyday infrastructure over the next 10–20 years, today's niche players could look like buying early cloud or GPU leaders before the world catches on. Here are two quantum names with very different approaches that could, in a bullish scenario, move the needle on lifetime wealth and eventually produce some millionaire investors.

This month, the company reiterated that its systems are already accessible via major public clouds and are being used by customers in pharmaceuticals, materials, finance, logistics, cybersecurity, and government work. What makes IonQ interesting from a millionaire‑maker perspective is the combination of three things: A credible technical roadmap (including industry‑leading error rates on key two‑qubit gates). Distribution through hyperscale clouds that can switch on demand when the economics make sense. Early‑stage real workloads and partnerships rather than purely academic demos. In other words, IonQ looks like a potential millionaire maker because it has a real technical edge, major cloud distribution, and early partnerships, proving it's moving beyond lab demos into real-world use.

quantum-computingVanguard Owns 36 Million Shares of Rigetti Computing. Here's Why That $577 Million Position Doesn't Mean What You Think It Does.
Passive fund buying is not a vote of confidence.If you follow quantum computing stocks, you've probably seen some version of this headline: "Wall Street is loading up on Rigetti Computing (RGTI 4.07%)." The article in question probably pointed to 13F filings showing that leading money managers like Vanguard, BlackRock, and State Street hold tens of millions of shares of the pure play. At first glance, that might look like a massive endorsement. Vanguard, the largest asset manager on the planet, has a position in Rigetti worth roughly $577 million. That must mean something, right? Active vs. passive In fact, though, Vanguard's large position in Rigetti has nothing to do with the convictions of its fund managers. It exists because the stock is a component of broad indexes like the Russell 2000. Vanguard offers numerous passively managed funds -- like the Vanguard Small-Cap Index Fund -- that track a specific index. That means holding every stock in that benchmark index in the same proportion -- or weighting -- as the index does.

Some active hedge funds like D.E. Shaw also hold sizable positions in Rigetti. But those positions don't amount to much of an endorsement either. D.E.
